SUSTAINED RELEASE PARTICLES |
摘要 |
A method of preparing parenterally administrable sustained release microparticles, which comprises preparing core particles in an aqueous medium that is essentially free from organic solvent, a biologically active substance being entrapped therein during or after said preparation, drying the core particles and coating the same with a release- controlling polymer by air suspension technique so as to create a shell on the core particles without any detrimental exposure of the active substance to organic solvent. Microparticles obtainable by such a method.
